Simulation and Study of Catastrophe Phenomenon in Knowledge Collaboration Complexity Network

Knowledge collaboration network is a kind of complexity network, because of some special reasons, catastrophe phenomenon will appear in the knowledge collaboration complexity network, and the whole system will became low-efficiency or inefficiency. Based on the analysis of catastrophe phenomenon in the knowledge collaboration complexity network, this paper proposed a catastrophe model. Using with the dynamics simulation tool VERSIM, a dynamics model of catastrophe phenomenon in the knowledge collaboration complexity network is built. Moreover, some simulation results is given, which disposed some reasons of catastrophe phenomenon in the knowledge collaboration complexity network.
